General Question

How much ultraviolet light should I feed my eyes?

Someone just told me it’s a good idea to expose your eyes to at least a little bit of UV light. He said it prevents nearsightedness, and he told me his vision got better while he was in the military and didn’t wear sunglasses. I wear sunglasses all the time, and underneath them, I wear contacts (which do or do not block UV rays?). Am I doomed to perpetually degenerating long distance vision? Or might I be able to condition myself back to 20/20 with a little extra time in the sun?

” UVB rays are the ones that burn the skin and can damage the eyes. Combined with cold wind and snow, UVB has the potential to cause snow blindness (photokeratitis), a temporary (lasting 12 to 48 hours) but painful problem in the cornea of the eye.

Although not all scientists agree, there is some research that suggests that daily exposure to UVB in very bright sunlight over a period of many years may cause cataracts, a gradual clouding of the lens of the eye.

Experts also suspect that the primary cause of eye growths such as pingueculae or pterygia is exposure to UVB rays.”

“The children with the worst eyesight did lots of near work and spent very little time outside. Interestingly, the study found no benefit from playing sports indoors. “The crucial factor was being outdoors,” says Rose.

“Time spent outdoors, as a protective factor, now appears to be the strongest environmental factor that has yet been documented.”

UV radiation is harmful if overexposed, but our bodies still need it to produce vitamin D.

These Guys have some eye exercises that are supposed to help. I saw several testimonials that the Bates Method of “sunning” provides very fast and noticeable results. Don’t be so quick to dismiss things that are unfamiliar, the world is a complex place.
